Abstract

This paper re-proposes a synthetic method of estimation of safety, reparability and serviceability for buildings from a viewpoint of seismic risk based on author etc (2010). The seismic risk curves regarding death rate, loss and building downtime are assumed toshow safety, reparability, and serviceability in seismic performance. The effects of the interrelationship between the earthquake-motion and the building response characteristics on each seismic risk were analyzed in detail. The results showed that, because the contribution of the structural frame, nonstructural elements, and building equipments to seismic risk was greatly affected by theinterrelationship, there was a tradeoff relationship among the abovementioned seismic risks that depends on the evaluation conditions. This suggests the usefulness of determining seismic performance based on multifaceted seismic risk assessment.
